As teachers around the country are being flooded with holiday gifts from appreciative parents and students, we decided to ask the teachers who follow us on Twitter and Facebook what types of gifts they actually want to receive this year. A vast majority of respondents said all they really want is a simple thank you.
You also must decide how much to spend. Again, there's no set recommendation. In a survey of more than 1,000 people by retailmenot,respondents on average said gifts worth about $111 were appropriate for high-school graduates, $243 for someone earning a bachelor's degree and $256 for the recipient of a graduate degree.
